"The Force is, & always will be strong with females here on Earth & in galaxies far, far away," the actor wrote in part.

Mark Hamill and The Force are powerful allies.

On Wednesday, the sci-fi icon offered some sweet advice after he saw on Twitter that a young girl was scared to sport a Star Wars shirt at school because she believed she would be made fun of by those who think the films are for boys.

"My 7-year-old daughter's crying in bed right now because she wants to wear her Star Wars t-shirt to school but is scared her classmates will laugh because she likes 'boy stuff,'" tweeted N.J. Simmonds‏. "I'm so sad/angry for her. Please RT and comment so I can show her how awesome girl #StarWars fans are."

Hamill, also a social media Jedi Knight with millions of followers across his platforms, responded to the distressed mother.

"Just tell her to feel free to use this gesture if her classmates give her any grief. 'Boy stuff'? PLEASE! The Force is, & always will be strong with females here on Earth & in galaxies far, far away. - mh," Hamill wrote, along with a GIF of Luke Skywalker brushing off his shoulder from a classic moment in The Last Jedi.

Hamill be be honored Thursday with a star on the Hollywood Walk of Fame. Harrison Ford is among those slated to speak.

On Wednesday, Hamill had a bit of fun and pretended to destroy Jimmy Kimmel's star to make way for his own.

Just tell her to feel free to use this gesture if her classmates give her any grief. "Boy stuff"? PLEASE! The Force is, & always will be strong with females here on Earth & in galaxies far, far away.
